“Because of the possibilities for multiplication inherent in the grid form, a basic and seemingly unlimited vocabulary was at LeWitt's disposal... [the] serial form produced multipart pieces of finite order but infinite complexity” (A. Legg, Sol LeWitt, exh. cat., Museum of Modern Art, New York, 1984, p. 9).
“When an artist uses a conceptual form of art, it means that all of the planning and decisions are made beforehand and the execution is a perfunctory affair. The idea becomes a machine that makes the art... Conceptual art is not necessarily logical. The logic of a piece or series of pieces is a device that is used at times only to be ruined. Logic may be used to camouflage the real intent of the artist, to lull the viewer into the belief that he understands the work, or to infer a paradoxical situation (such as logic vs. illogic)... Ideas are discovered by intuition.” – Sol LeWitt
